IWC HERITAGE BIG PILOT 7-DAYS – Ref. IW501004 – Titanium – Black Dial – 46.2mm – Brown Leather Strap – Box & Papers – 2023 – Unworn – Full Set

We are pleased to offer this exceptional IWC Big Pilot’s Watch Heritage Ref. IW501004, a modern tribute to the legendary B-Uhr observation watches of the 1940s, presented here in ultra-lightweight titanium and offered in unworn condition.

The 46.2mm titanium case offers a dramatic presence on the wrist, while remaining significantly lighter than its stainless steel counterparts. Its matte finish underscores the utilitarian character of the watch, perfectly complemented by a large onion-shaped crown designed for ease of operation — even with gloves.

The matte black dial is pure instrument-style legibility, featuring luminous Arabic numerals, sword-shaped hands, and a classic triangle at 12 o’clock, along with a power reserve indicator at 3 o’clock and a date aperture at 6.

Inside beats the IWC-manufactured Caliber 52110, a twin-barrel automatic movement offering an impressive 7-day power reserve. It features a Pellaton winding system with ceramic components, and is visible through the sapphire exhibition caseback — a modern luxury added to a historically inspired design.

The watch is fitted with a brown calfskin leather strap with contrast stitching and secured by a titanium tang buckle. It is accompanied by a complete full set, including:

- Original IWC presentation box

- Certificate of origin & warranty card (dated 2023)

- Instruction manuals

“A faithful reinterpretation of IWC’s aviation heritage!"
